ApneaTraining

A C program to improve CO2 tolerance for sleep apnea using breath-hold exercises adapted from freediving CO2 tables.

Why train CO2 tolerance to beat sleep apnea?

If there is no compiled binary you can

Compile it, run:

gcc -o apneaTraining apneaTraining.c
./apneaTraining

## Overview

This project provides a command-line tool to train CO2 tolerance, helping users breathe more steadily to reduce sleep apnea symptoms. It includes three training modes:

### Training Modes
Type A - Fixed Breath Hold, Decreasing Rest. Short session.

Type B - Increasing Breath Hold, Fixed Rest. Short session.

Type C - Fixed Breath Hold, Fixed Rest, Infinite Loop. Also known as tidal breathing. Can be as long as you want it.

The program measures a "Relaxed Pause" (breath-hold time after exhale) and saves it to `relaxedPauseData.txt` for progress tracking

## Usage

### Running Binaries
Precompiled binaries are provided in the `bin` folder:
- Linux: `apnea_linux`

Download the appropriate binary and run:
- Linux:
  ```bash
  chmod +x bin/apnea_linux
  ./bin/apnea_linux

Compilation Instructions

Linux

1. Install GCC:

   sudo apt-get install gcc

2. Compile:

   .../ApneaTraining$ gcc -Wall -std=c11 apneaTraining.c -o ./bin/apnea_linux

3. Run:

   ./bin/apnea_linux

Requirements

• Linux: GCC, Ubuntu linux has been tested. (Needed for unistd.h, sleep)

Notes

• The program creates and reads from relaxedPauseData.txt in the working directory. [todo: use ini file instead]
